Title: Improvements in or relating to electronic counting circuits
IPC: H03K29/00
Filed: 1953-09-29
Abstract: 768,550. Counting-apparatus; electric digital data-storage apparatus. ERICSSON TELEPHONES, Ltd., and BURNETT, L. C. Dec. 29, 1954 [Sept. 29, 1953], No. 26693/53. Class 106 (1). [Also in Group XL (c)] In counting-apparatus, input pulses are applied to a first multi-gap discharge tube and pulses are applied from an independent pulse source through a gate circuit to a second multigap discharge tube, each cathode of which is connected to a corresponding cathode of the first tube, only when the discharges in the two tubes pass to unconnected cathodes. Each pulse passed by the gate circuit is applied also to a counter which, according to the Provisional Specification, may be as described in Specification 712,171. For counting random pulses from several sources, e.g. turnstiles, each source, e.g. 12, Fig. 1, is connected to a first tube 10 associated with a second tube 11 to which pulses are applied from a gate 15 controlled by coincidence - detecting arrangements 14 and the several gates 15 are pulsed sequentially by a thermionic or commutator distributer 17 supplied from a source 16. The outputs of the gates 15 are connected over isolating diodes to the counter 20. At each source, the input and gated pulses respectively are applied to the first and second tubes CTA, CTB by 'drive circuits 23, 24 and, for detecting, coincidence of registration in the two tubes, the anode potential of the first is modulated from a high-frequency source IS1. When coincidence occurs, this modulation is passed to the anode of the second tube, by virtue of the connected cathodes and is applied via GA to a valve VC, Fig. 3, having an anode circuit tuned to the modulation frequency. The coincidence signal is then rectified and applied to a pentode gate VD to which are also applied the pulses from the distributer IS3, 17. The pentode gate thus passes the latter pulses only in the absence of coincidence. While the discharge in either tube of a pair passes to a guide electrode, the drop in the cathode potential via GB biases off the gate pentode VD. The output pulses are shaped by a monostable multivibrator VE and applied via GC to the second tube CTB and over a diode W4 to the total counter. Specification 712,215, [Group XL (a)], also is referred to.

Filed: 1961-07-31
Abstract: 941339 Super-conductor materials WESTERN ELECTRIC CO Inc 31 July 1961 [9 Jan 1961] 27696/61 Headings H1A A5 and A4D A super-conductive element is made by filling a cylindrical container with powdered material comprising a compound of Formula Nb 3 Sn or materials which can react to form the compound, mechanically reducing the cross-section of the container by at least 60% and the heating to form the powdered material into a solid mass of the compound. The powdered material may be a mixture of niobium and tin in stoichiometric proportions or a mixture of Nb 3 Sn or the constituent metals thereof with 1-20 wt. per cent (preferably 10%) of tin. The resulting materials exhibit critical fields and currents higher than those of materials of the same composition obtained by solidifying a molten mass. In a typical embodiment the powdered material is tamped into a niobium plugged niobium tube 2 inches long with internal and external diameters of # inch and  inch respectively and the open end sealed with a niobium plug. After cold swaging to an internal diameter of 30 mils. the tube is reduced by drawing through a series of dies to an internal diameter of 6 mils., cut into 3-inch lengths and heated, typically to 970-1200C. for 16 hours, in vacuum. The critical currents for various magnetic field strengths determined experimentally on materials produced in this way using different starting mixtures, temperatures and duration of heating, and without and with different amounts of mechanical reduction of the tube are given and discussed. In general, the critical current in a standard sized specimen increases as the mechanical reduction is increased. Optimum values of critical current are obtained with temperatures of 900-1000C. maintained for 12-20 hours and a mechanical reduction of internal cross-sectional area of the tube of about 99%. Pure Nb 3 Sn gives a higher critical current than materials with an excess of tin. In a known method referred to, stoichiometric amounts of tin and niobiam powders after sintering at 1800C. are melted in a zirconia crucible in argon gas at 2400C. and then solidified to form an ingot from which strips are cut.
